CXR5 SERIES
Thank you for purchasing the Entel CXR5
bone conductive headset. This user guide
will explain the features of your microphone,
which with care should provide many years of
trouble free operation.
The CXR5 is a high-performance bone
conductive headset that delivers clear,
intelligible audio transmissions, even in high
ambient noise environments.
FITTING
The CXR5 should be mounted securely inside
your helmet so that it sits on your head, as shown
on the cover image. Adjust the fitting to ensure
that the bone conductive microphone makes firm
contact with the top of your head. Connect the
audio connector of the CXR5 to the PTT unit
OPERATING INSTRUCTIONS
• Insert the Nexus connector of the CXR16
directly into the PTT unit.
• Attach the PTT unit to a pocket or collar
using the clip on the rear of the unit.
• Press the PTT button to transmit and
release to receive.
IMPORTANT
Always switch the radio o before
attaching an audio accessory. Models that
are certied to ATEX & IECEx have been
clearly labelled. Should, in the course of
use, any labels be removed or become
illegible please return the accessory to
Entel for relabelling.
Please note that the use of a connector
other than the Nexus connector may
damage the socket and invalidate the
warranty.
